I am facing serious problems when I zoom in and out because the response is extremely slow, while I can rotate the model normally.
I have already tested the graphic card with the utility "mesa-util" and it seems that the 3D and 2D acceleration is working properly (at least from the visualized "gear" of mesa-util). I have faced the same problem with Ubuntu 14.04 LTS and therefore I decided to switch back to 12.04, because I did not have any problems while using Paraview with Ubuntu 12.04 from a Live USB stick.
